I think it's more likely a side-effect of neurodivergence. I don't identify with the symptoms that google spit out, and autism is known to be correlated to a "mistuned" gut. I have been diagnosed with asperger, although that diagnosis has since been rescinded (no diagnosis to replace it however). All I can say for sure is that there is a deviation from normal in the way my brain works.

And when I say high sugar intake, I truly do mean high. I can and will eat ~500g of candy in one sitting if I have unfettered access to it.
